A radial mode helix can and does work, despite Art`s apparent
disputation.

The radial mode helix acts as a stacked horizontal loop antenna. Hams
routinely use horizontal loops for more bandwidth with less drivepoint
resistance variation in a centerfed half wavelength of wire. When the
length of wire goes from 0,5 WL to 0.6 WL the dipole increases its
resistance from 70 ohms to 140 ohms. The loop feedpoint increases from 5
ohms to 7 ohms (theat`s less than a double as in the dipole. This
information is found in Figs 7-19 and 8-14 of Bailey`s "TV and Other
Receiving Antennas".

Richard, look again at the phrase "resultant vector"
which means it is one vector.
This angle is reflected by the "Pitch" in a
helical antenna.
All the other words are unnessesary and non relavent
with respect to RESULTANT VECTOR.
